Title: Improvements in or relating to television and the transmission of pictures with sounds appropriate thereto
IPC: H04N5/84
Filed: 1933-08-14
Abstract: 428,852. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd., Blyth Road, Hayes, Middlesex, BROWNE, C. O., 29, Monks Drive, West Acton, London, and HARDWICK, J., 66, Drayton Gardens, West Drayton, Middlesex. Aug. 14, 1933, No. 22720. [Class 40 (iii)] In a film television system the signals are derived from a kinema film having an " intensity con. trast " substantially less than 1 : 8 which represents the intensity contrast of normally developed films. The object or scene may be photographed on a film which is treated to produce a negative with an " intensity contrast " considerably greater than unity and preparing from the negative a positive with a lower " intensity contrast " than the negative and employing the positive for transmission. At the receiver means are incorporated for reproducing the film with a higher " intensity contrast " than that transmitted, and when the signals are applied to a cathoderay tube the latter may be designed, in conjunction with the voltages applied to its electrodes, to effect the appropriate increase in the " intensity contrast " in the picture reproduced. A valve working from a point 1 on its curved characteristic, may precede the cathode-ray tube when the latter does not sufficiently increase the " intensity contrast " of the reproduced picture. When the receiving light-source is a Neon tube the " intensity contrast " may be increased by a valve operated as indicated in the Figure. The direct and lowfrequency components of the picture signals may be reinserted, if necessary, in the manner described in Specification 422,906. When the picture has a sound accompaniment, the picture and sound signals are transmitted with an effective " intensity contrast " of substantially unity and at the receiver the " intensity contrast " of the picture signals is increased whilst that of the sound signals is substantially not changed.

Patent GB-1075049-A (GB)
Title: Recovery of iodine
Inventor: WOOD PETER WORSLEY SPENSER
IPC: C01B7/14
Filed: 1964-07-08
Abstract: Iodine is recovered from an aqueous solution of an iodide salt by alternately contacting an anion-exchange resin with chlorinated and non-chlorinated portions of the aqueous solution, whereby the resin picks up iodine, eluting iodine from the exchange resin and recovering free iodine from the eluate.  The chlorinated solution preferably contains 1-5 moles of chlorine per equivalent of iodine. Sodium hydroxide or sodium chloride may be used for eluting the iodine from the resin and the free iodine may be recovered in the case of elution with NaOH by the addition of a mineral acid and sodium iodate to the eluate.  Alternatively, the elution may be effected using sodium hydroxide and then sodium chloride as eluants, which process is described in Specification 1,058,429 from which the present application is divided.  The ion-exchange resin may be a strongly basic quaternary ammonium resin or a weakly basic resin, e.g. of the polyamine type, both being in either the salt or hydroxide form.  In a preferred method of working the chlorinated and non-chlorinated solutions are passed alternately through 2 anion-exchange resin columns in series until the first column is exhausted, then the solutions are passed through the second and a third column of freshly regenerated resin while iodine is eluted from the first column.
